- 0.144u4: Added, and made Mr. Do! use the U8106 soundchip, which as far as I can tell is 100% identical to the SN76489 non-a, pending further testing [Lord Nightmare, plgDavid]. Replaced the 2x SN76489 sound with U8106 (SN76489).

- 31st October 2011: Mr. Do - Thanks to inspiration from kelly, I gave the Mr. Do bezel the proper treatment. I taught myself how to use the pencil tool properly in Photoshop, and based on the scan from the BYOAC/CAG artwork, and various photos, I'm finally happy with the end result. We also learned that the original Mr. Do bezel had a pink border around the screen; the blue border version is for conversions. This updates the files for mrdo, docastle, sraider and jjack. Mr. Do also includes the marquee, which is based on zorg's vector work, the BYOAC/CAG version, and photos, to make sure that I got the colors and alignment on the inside of the marquee correct. I'll add the control panel and instruction sticker later, once I finish them correctly.

- 22nd February 2010: Mr. Do - Until such time that Zorg finishes up vectoring the Mr. Do bezel, I figured I could at least semi-correct the current vector version, so the Universal bezel has been brightened up and replaced for Mr. Do, Mr. Do's Castle, Jumping Jack and Space Raider.

- 0.136u3: Oliver_A and Tafoid fixed incorrect XTALs in Mr. Do! cause for problems with refresh rate and game speed. Changed Z80 CPU1 and the 2x SN76489 clock speeds to 4.1MHz and VSync to 59.943237.

- 9th July 2008: Mr. Do - Added the Gleeb Company version bezel to Mr. Do, scanned and vectored by Jeff Rothe. Also found part of a conversion overlay, and was able to recreate the conversion bezel I had played on so long ago.

- 11th February 1999: Mirko Buffoni has made the interpolation stuff even better. Exed Exes example is about doubling with 50% transparent scanlines (left side), and Mr. Do! example is about doubling with linear interpolation (both sides) and 50% transparent scanlines (left side). All these things are of course off by default.

- 6th February 1999: Mirko Buffoni has made interpolation routines for MAME. You'll need a powerful machine for this: (it's like ZSNES).

- 0.30: Lee Taylor added clone Mr. Du! (bootleg 1982). Tatsuyuki Satoh and Nicola Salmoria cleaned up the SN76496 emulation, now it is similar to the 8910 one and all games use Tatsuyuki's code. This affects several games, most notably the Mr. Do! series.
